QTR-Quadtone RIP

Hello everybody, I've just subscribed to this forum!
I'm an amateur photographer, you can see some of my pics at:
http://www.photo.net/photodb/member-photos?include=all&user_id=686910
Some of them have been published on Italian magazines.
Lately I've started being interested in B/W, and that's the reason why
yesterday I've downloaded QuadToneRIP 2.4.1 and I've installed it on
my Mac G4, OSX,10.4.5, PSCS2, Epson R800.
I've read the User's Guide but it seems to me that they are speaking
of something rather different. I can't find the application they are
speaking about! I've tried printing some photos playing with different
settings found in the "print" menù, but the result were very very pale
prints.
Is there an updated User Guide? Did I do something wrong installing
it? Can anybody help me? Thank you so much, Carlo
